find out why:
xen do (not by its choise, it's a "bug"):
eth1 - xenbr1 - veth1 - ifconfig veth1 up
                      \ vconfig add veth1 600 - veth1.600 - xenbr1.600
                      \ vconfig add veth1 14 - veth1.14 - xenbr1.14

so now:
how can i manage something like:

eth1 - xenbr1
     \ vconfig add eth1 600 - eth1.600 - xenbr1.600
     \ vconfig add eth1 14 - eth1.14 - xenbr1.14

in first (working) scenario, the problem is that ALL traffic goes through 
xenbr1... with one more step against second scenario.
